El trabajo propone un recorrido por la historia hispanoamericana del siglo XIX, a fin de recuperar para la reflexión presente las formulaciones más destacadas de la vastísima tradición intelectual de la unidad continental, así como también los antecedentes, menos prolíficos pero no por ello menos importantes, de una teoría de la democracia en un sentido amplio, popular y participativo. El cruce de estas dos vertientes del pensamiento de nuestra América constituye en conjunto un programa identitario que todavía nos interpela y (...) que tiene mucho para aportar a los proyectos presentes y futuros de la patria latinoamericana.

La autora presenta al “Estado de derecho” como un campo de lucha. Desde arriba, se busca conferirle ese estatuto al nuevo poder mundial, correlato y brazo político-militar de las burocracias privadas. Es la estrategia de globalización –que reduce la democracia a puro procedimentalismo formalista- y que no puede sino generar desde abajo resistencias mundiales: resistencias programáticas y organizadas que buscan construir otro mundo posible, por un lado, y por otro lado resistencias irracionales, sin capacidad de articulación política. La autora recorre (...) el pensamiento de Hinkelammert, destacando la crítica que elabora al fetichismo de la mercancía, del dinero y del capital y su planteamiento de un conflicto entre rebelión legítima frente a la ley despótica e idolatría de la ley.

La figura del chileno Francisco Bilbao (1823-1865), como pensador americanista y crítico de las filosofías de la historia eurocentristas, constituye el hilo central de este análisis. La autora expone los elementos claves de la crítica de Bilbao respecto de los sistemas de pensamiento que promueven una aceptación pasiva del pasado y el presente como un designio de la Providencia o bien del Progreso. Se develan las lógicas que existen tras las distintas versiones de la filosofía de la historia, como teoría (...) justificadora del relato de los vencedores sobre los vencidos, como así de las intenciones hegemónicas de los países centrales respecto de las nacientes repúblicas latinoamericanas del siglo XIX. El carácter visionario y libertario de Bilbao es destacado por la autora, especialmente en cuanto forjador de una original teoría crítica de la historia con raíces americanas. (shrink)

Modern zoos strive to educate visitors about zoo animals and their wild counterparts’ conservation needs while fostering appreciation for wildlife in general. This research review examines how zoos influence those who visit them. Much of the research to-date examines zoo visitors’ behaviors and perceptions in relation to specific exhibits, animals and/or programs. In general, visitors have more positive perceptions and behaviors about zoos, their animals and conservation initiatives the more they interact with animals, naturalistic exhibits, and zoo programming/staff. Furthermore, zoo (...) visitors are receptive to conservation messaging and initiatives at zoos, and are more likely to participate in on-site conservation opportunities as opposed to after their visits. The research also suggests that repeat visitors are even more inclined to seek out conservation efforts compared to those visiting zoos for the first time. While current research suggests that repeat-visitors are more likely to engage in conservation efforts, little is known about causal factors related to such findings, and almost no research exists to-date comparing the conservation efforts of visitors vs. non-visitors. This latter comparison will likely play a greater role in future zoo visitor research, since it poses one of the most important metrics for evaluating the specific effects visiting a zoo can have on people engaging in conservation efforts in general.

In this work we define, in a general way, an algebraic semantics for the logics of the hierarchy InPk. This semantics is defined by means of an alternative construction, with respect to the usual algebraic semantics, and it is known in the literature as Twist-structures semantics. Besides that, we modify such construction, defining the so-called ω-Twist-structures here. This adaptation allows us to prove adequacy theorems for every logic of the hierarchy InPk.

The objective of this article is to assess the impact of generative artificial intelligence (AGI) as a learning tool in clinical practice, as perceived by clinical students of human medicine. To this end, six learning activities were devised and executed, employing diverse pedagogical approaches and AGI tools, with the objective of addressing various facets of clinical practice. These included the creation of explanatory material, literature analysis, the selection of clinical cases for publication, the development of self-assessment questions, the production of (...) explanatory videos, and the creation of scientific posters. These activities were conducted during the clinical internships of the fifth year of the medical curriculum and were evaluated using both quantitative and qualitative methods. The findings indicated that the incorporation of GAI as a pedagogical instrument in the clinical training of medical students yielded a favorable influence on their motivation, self-assurance, satisfaction, competencies, and knowledge. The students identified GAI as a novel, applicable, useful, and transferable tool and expressed interest in continuing to use it in the future. However, the results also indicated that students encountered certain challenges and difficulties in utilizing GAI as a learning tool, including overconfidence, resistance, and a lack of understanding. In conclusion, this study provides empirical evidence on the use of GAI as a learning tool for undergraduate medical students' clinical practices, and contributes to the knowledge base regarding the possibilities and challenges of GAI application in higher education.

El libro de Michael Heinrich tiene el doble mérito de presentar una mediación de la obra cumbre de Karl Marx, redactada en un lenguaje claro y accesible, y de proponer, al mismo tiempo, una interpretación densa y erudita del famoso texto. El autor no sólo evita las simplificaciones y los esquematismos, sino que incluso se interna por las complejidades y paradojas del pensamiento marxiano, que han dado origen a discusiones y polémicas nunca saldadas, y nos ofrece siempre una posición argumenta..

Using microdata from the Wage Structure Survey, we analyse the gender wage gap in the private and public sectors, considering the whole wage distribution. The main contribution is to assume that the decision to work in a sector is a prior process determined endogenously in the model. Thus, the usual Ordinary Least Square estimation is inconsistent, and it is necessary to use alternative techniques. We use quantile regression techniques to calculate how much of the gap is due to differences in (...) returns between men and women and sectors, taking into account the sample selection bias. We find that the size of the gap attributed to different returns varies substantially across the wage distribution. Public sector employees are paid higher wages, on average, than their counterparts in the private sector, and the gap is wider for women. Moreover, the proportion of the gender wage gap explained tends to be greater for workers who are at the bottom of the wage distribution in both sectors. A look at the whole wage distribution reveals that discrimination in the gender wage gap is typically higher at its top than at its bottom, suggesting that glass ceilings are more prevalent than sticky floors for both men and women.

The multilinear extension of a cooperative game was introduced by Owen in 1972. In this contribution we study the Lovász extension for cooperative games by using the marginal worth vectors and the dividends. First, we prove a formula for the marginal worth vectors with respect to compatible orderings. Next, we consider the direct market generated by a game. This model of utility function, proposed by Shapley and Shubik in 1969, is the concave biconjugate extension of the game. Then we obtain (...) the following characterization: The utility function of a market game is the Lovász extension of the game if and only if the market game is supermodular. Finally, we present some preliminary problems about the relationship between cooperative games and combinatorial optimization. (shrink)

The putative Pueyo’s vaccine was a commercial venture that obtained marketing authorization in 1946, a turbulent period of Argentine history. After a few months, health authorities withdrew financial support from the state to buy the vaccine and required patients to sign a written consent to receive that product. An independent investigation did not find any evidence of benefit in non-clinical and clinical evaluation of the putative vaccine.

This introduction to the Journal of Business Research special issue on anti-consumption briefly defines and highlights the importance of anticonsumption research, provides an overview of the latest studies in the area, and suggests an agenda for future research on anti-consumption.

Genomic research may uncover results that have direct actionable benefit to the individual. An emerging debate is the degree to which researchers may have responsibility to offer results to the biological relatives of the research participant. In a companion study to one carried out in the United States, we describe the attitudes of Canadian Research Ethics Board chairs to this issue and their opinions as to the role of the REB in developing related policy.

ABSTRACTPolitical actors use metaphor in their speeches in order to frame political issues [Charteris-Black, J.. Politicians and rhetoric: The persuasive power of metaphor. Basingstoke: Palgrave Macmillan]. If they succeed in imposing a particular frame, especially when there is no agreement on the definition of certain political issues, this can become the prevailing way for referring to that issue [Semino, E.. Metaphor in discourse. Cambridge: Cambridge University Press]. In this research, we argue that this was the case for the metaphor of (...) the JOURNEY in the Catalan political conflict during electoral periods. To that end we use Critical Metaphor Analysis [Charteris-Black, J.. Corpus approaches to critical metaphor analysis. Basingstoke: Palgrave Macmillan] to analyse televised campaign ads from the last three elections for the Parliament of Catalonia – from 2010, 2012, and 2015 – in order to identify how political actors’ use metaphors to talk about the Catalan political situation during these years and to verify if JOURNEY metaphor resulted into the dominant narrative. The results show that the political situation has been conceptualized in terms of a ‘process en route,’ although the narratives generated by the political actors that shaped that discourse differ.

Childhood obesity, linked to a sedentary lifestyle and an unbalanced diet, is one of the main problems in today’s Western societies. In this sense, the aim of the study was to analyze students’ perceived satisfaction in physical education classes with learning strategies and engagement in learning and critical thinking as determinants of healthy lifestyle habits. The study involved 2,439 high school students aged 12–18 years (M= 14.66,SD= 1.78). Structural equation modeling was conducted to analyze the predictive relationships between the study (...) variables. The results showed that teaching, teaching mastery, and cognitive development are precursors to deep thinking on the part of students, indicators of the adoption of healthy lifestyle habits. These results reflect the importance of the methodology adopted by the teacher in order to positively influence the students’ habits. (shrink)

The aim of the research was to know the perception of high-level volleyball players of the changes produced in the efficiency of the training process, after a match analysis intervention program based on the Constraint-led Approach. The sample consisted of 11 players from a women's volleyball team. The protocol of the intervention program consisted of providing objective, contextualised and systematic information to the coach that would allow understanding the different real game contexts. We used semi-structured interviews to assess players' perceptions. (...) The athletes perceived changes in training, both in their preparation and development, specifically in greater involvement and organisation in preparing the training; in an increase in the specificity and suitability of training tasks according to individual needs; in the representativeness of the restrictions of the game; in a more tactical approach; in the variability of task and in the accountability to achieve the objective proposed. In addition, in the preparation and development for competition, the players detected more game planning; a deeper analysis of the opponents; an objective selection of the most relevant data, an increase in the depth of match analysis and the inclusion of the weekly meeting with the use of video compared to the previous season. These results expose the benefits of coaches incorporate programmes to obtain objective information about the game in their training process. (shrink)

Este trabajo analiza el papel de los suidos en la ritualidad protohistórica japonesa, tomando como base la aparición de una serie de restos óseos de estos animales en contextos rituales y/o con indicios de consumo ritual, especialmente en los periodos Jōmon (ca. 10,500-300 a.n.e.) y Yayoi (1,000-900 a.n.e.-250-300 d.n.e.),. Pero antes de entrar de lleno en la problemática de estos ejemplares, es necesario realizar una retrospectiva del papel de dichos animales en el archipiélago japonés desde la Prehistoria, así como de (...) la propia domesticación del cerdo en el continente asiático y su difusión por Asia Oriental hasta llegar a las islas japonesas. A este respecto, hay que tener en cuenta que existen tres ámbitos de estudio diferenciado en lo referente a los suidos en el archipiélago japonés: Hokkaidō, el archipiélago de las Ryūkyū y las islas de Kyūshū Honshū y Shikoku.
